Anterior Crossbite in dogs and cats

Description

Anterior cross bite occurs in dogs when one or more of the front teeth (incisors) are out of position. Anterior cross bite is a common mismatch of tooth position (malocclusion ) in dogs, and can cause damage or abnormal wear to the front teeth.

anterior cross bite - malocclusion where the one or more of the maxillary incisors lie distal to maxillary incisors. Anterior cross bite only affects the incisor teeth

Normal scissors bite; lower canine fits between upper third incisor and the upper canine. Also notice the interdigitation of upper and lower premolar teeth (side view).

Anamnesis

Causes

Anterior cross bite can be caused by one or several factors. Anterior cross bite can be caused by crowding of the teeth if the face is too narrow, or even by a jaw of abnormal length. Sometimes if the teeth do not overlap, they will be in an abnormal position.

Diagnosis

Anterior cross bite is diagnosed by performing a full examination of the head, jaw, and teeth.
